Wie so oft ist es in der API ganz einfach… Im Scripting muss man aber einmal einen Roundtrip machen…
Hier eine Action um die Anzeigesprache des Projektes per Script zu ermitteln.

Aufruf:

public void Function()
{
  var languages = GetDisplayLanguages();
  foreach (var language in languages)
  {
    MessageBox.Show(language);
  }
  return;
}

private static List<string> GetDisplayLanguages()
{
  string value = null;
  ActionCallingContext actionCallingContext = new ActionCallingContext();
  new CommandLineInterpreter().Execute("GetDisplayLanguages", actionCallingContext);
  actionCallingContext.GetParameter("value", ref value);
  var split = value.Split(';');
  var languages = split.Where(language => !string.IsNullOrEmpty(language)).ToList();
  return languages;
}

 

Script:

namespace EplanScriptingProjectBySuplanus.GetDisplayLanguages
{
    public class GetDisplayLanguages
  {
        [DeclareAction("GetDisplayLanguages")]
        public void Action(out string value)
        {
            // Get language from settings
            string tempFile = Path.Combine(PathMap.SubstitutePath("$(TMP)"), "GetDisplayLanguages.xml");

            ActionCallingContext actionCallingContext = new ActionCallingContext();
            actionCallingContext.AddParameter("prj", FullProjectPath());
            actionCallingContext.AddParameter("node", "TRANSLATEGUI");
            actionCallingContext.AddParameter("XMLFile", tempFile);
            new CommandLineInterpreter().Execute("XSettingsExport", actionCallingContext);

            // Needed because there is no direct access to setting
            string language = GetValueSettingsXml(tempFile, "/Settings/CAT/MOD/Setting[@name='DISPLAYED_LANGUAGES']/Val");
            value = language;
        }

        private static string GetValueSettingsXml(string filename, string url)
        {

                string value = rankListSchemaName[0].InnerText;
                return value;
            }
            return null;
        }

        private static string FullProjectPath()
        {
            ActionCallingContext acc = new ActionCallingContext();
            acc.AddParameter("TYPE", "PROJECT");

            string projectPath = string.Empty;
            new CommandLineInterpreter().Execute("selectionset", acc);
            acc.GetParameter("PROJECT", ref projectPath);

            return projectPath;
        }
    }
}
